    • 专利摘要:
    A disc cassette for a readable information disc (1) comprises an enclosure (2) in which the information disc is situated with clearance and which enclosure comprises parallel main walls (3A, B), side walls (4A, B; 5A, B) and a rear wall (6A, B), a central aperture (7A, B) being formed in at least one of the main walls to provide access to the information disc for the drive spindle of a drive apparatus, and a slot (8A, B) for the passage of a recording and/or reproducing head of the drive apparatus, which openings can both be closed by a slidable shutter (9). The disc cassette comprises a slide (11) which is slidable on the enclosure with the aid of parallel guide means, to which slide the shutter (9) is rigidly connected, so that the slide and the shutter are together movable between the operational position and the closed position.

    using parallel guides, the shutter 9 is rigidly attached to the carriage so that the carriage and the shutter can move together between the working and closed positions, 2 h, n, 3 silt
    The invention relates to the field of instrumentation and can be used to store an information disk.
    The purpose of the invention is to increase the reliability of the design,
    Fig. 1 shows a disk cartridge, closed state), general view; fig 2 is the same open state; FIG. 3 shows a detail of a disk cartridge,,
    The disk cassette contains an information disk 1, for example magnetic or optical ,. The casing 2, in which the information disk is located, contains two cheeks 2A and 2B attached to one another. The casing contains parallel main walls. ZA and BZ, which are connected by side walls 4A, 4B and 5A, 5B, respectively, and the back wall 6A and 6B. The two main walls, ZA and ZV, are provided with a central hole, 7 drive spindle (not

    Each of the central apertures is configured as a slot 8A and 8B, respectively, for accessing a recording device and / or combining information such as, for example, a magnetic or optical recording / reading head,
    The gap 9 is moved outside the co cl. The ka and in the closed position (Fig. 1) closes the central openings of the TAe 7B and the grooves 8A, 8B. In Fig. 2, the shutter 9 is shown in the working position in which the said openings are open.
    The information disk 1 has a central opening 10, and the central openings 7A and 7B in the two main walls provide access to said central opening for said spindle of the drive unit.

    The disk cassette comprises a carriage 11, which can slide along, parallel guides. The shutter 9 is rigidly connected to the carriage 11 so that the carriage and the shutter together move between the operating and closed positions,
    To move the carriage from the operating position to the closed, provided elastic device 12 in the form of a spring,. which acts on the carriage 11, a snap-in device 13 is provided for snapping the bolt in the closed position, which also cooperates with the carriage 11, to move the carriage from the closed position to the working position by means of the displacement means of the driving device the sides of the constriction 16,. Thus, with the elastic device 12, the locking device 13 and the moving device of the driving device only the carriage 11 interacts, i, e, without real interaction with shutter 9,
    The carriage 11 is moved along the front side of the casing 2 and is installed between the two main walls ZA and ZV, Dn this main walls are equipped with guide rails 17A and 17B, respectively, and the carriage 11 with corresponding guide grooves 18A and 18B the side of the carriage 11, which is facing outward the casing. The shutter has two tabs 19, and the carriage 11 is provided with two elastic hooks 20 for securing the tabs.
    The latching device 13 contains an axially movable pin, which moves elastically between the closed position and the released position in which it moves inside the disk cartridge. In the closed position of the shutter (Fig. 1), the snap pin 21 enters the constriction 16
    carriages. Thus, by means of the displacing means provided in the drive device for moving the shutter 9 to its working position, the latch pin 2 can be pressed inward to its release position. This allows the thief to complete the required movement. From the working position back to the closed position, the shutter is moved by means of an elastic device 12, which is automatically latched. For this purpose, the carriage II is provided with an inclined surface 22. When the carriage moves back, the latch pin 21 is gently pressed with the inclined surface inwards until the latch pin engages with the taper 16 and is spring-loaded into the latched position. (
